Spotting & Ubat Duphaston

Hi ibu2 yg ada pengalaman, smlm sy scan 6w5d dah ada heartbeat. Doktor bg ubat kuat rahim duphaston sbb sy pernah miscarriage & start pagi td sy ada spotting brown. Ibu2 kt sini ada tak pengalaman mkn ubat ni? Normal ke ye kalau mkn dia ada spotting? Berapaa lamaaaa spotting stop lepas mkn ubat ni? #pleasehelp
